IMPROVEMENT IN HARVESTER-CUTTER HOLDERS.

To all whom, fit 'may concern:

Be it known that I, SILAS H. WILSON, of the city7 of Auburn, in theState of New York, have invented a new anduseful device for holding thesickle-bars or knives of reapers and mowers in grinding, which I call AHarvester-Cutter Holder; and l do hereby declare that the following isafull, clear, and exact description of the construction and operation ofthe saine, reference being had to the annexed drawings, making part ofthis specication, in which- Figure l is a perspective view of one of theholders as applied to the cutte'rs, and

Figure 2 is a vertical section through its centre', showing thearrangement of the several parts.

The same letters in each ligure indicate like parts of the device.

In sharpening the cutters of'harvesting-machines,'

great difliculty isexperienced in holding them properly to the stone,their form being such that they cannot be conveniently held in thehands, and danger of injury to the hands always attends the operation,together with annoyance from the tilt-hy wate'r flowing from thegrindstone over the hands.

To overcome these difficulties and objections is the object of theinvention; and

It consists in the application of adjustable handles to the cutters orsickle-bars of harvesters, so that the Operator can firmly and safelyhold the same for the purpose of sharpening or grinding.

A represents the l'iandle-part of the device, which may be lmade ofmetal, of any convenient form, anc hollow, to give it lightness.

The lower end of the handle is spread ont, so as to forni lips, B, atright angles to it, or the lips may be made separate from thehandle-part, in the form oi' a bung-washer.

A spindle or bolt, G, having an elongated thin head or washer, D, at oneend, and a screw-thread formed on its other end, is inserted in thehandle-piece A, and a thumb-nut, 1G, is placed on the screw F of thespindle G.

When thus arranged, by turning the thumb-nut E, the head l) will bedrawn towards the lips B, so that anything placed between the parts Band D will be fastened and held as in.a vise.

By placing the parts B and l) on contiguous blades of the sickle, as iniig. 1, and turning the thumb-nut E down snug, the holder is rigidlyfixed to the sicklebar. Another similaiholder, being fastened to theother blades ai' convenient distance, enables the operator to seize andhold the sickle, with both hands, rinly to the grindstone, so ,as tosharpen it perfectly, with safety and rapidity.

A thinible or collar, of soft metal, G, may be placed.

on the spindle C, to protect the edges of the cutters from injury whenadjusting the handles, two of which, one for each hand, should beattached to the sickle or knife-bar.

It is evident that various modifications of the device and itsapplication may he made, without changing the character of theinvention.

What I claiin as new, and desire to secure by Letters Patent, isp The-adjustable handlesior holding reaper-knives to the grindstone insharpening, arranged and applied substantially as set forth.
